Original issue: phpstan/phpstan#9019
When we have a type defined such as
/**
* @phpstan-type FactoriesConfigurationType = array<
* string,
* (class-string<Factory\FactoryInterface>|Factory\FactoryInterface)
* |callable(ContainerInterface,?string,?array<mixed>|null):object
* >
*/
We get an error Unexpected token "|", expected '>'. According to the original issue the problem is caused by this package.
